Chapter 1 The Science of Biology
1) Science is subdivided into specific areas of study termed disciplines. These divisions are
artificial but are helpful to narrow the massive scope of scientific knowledge to a manageable
amount. Given what you know about each, which scientific division is likely to present the best
answer to a question about how fluid dynamics affect blood pressure in mammals?
A) Biochemistry – study of chemical reactions needed for life function, usually at the cellular
level.
B) Bioinformatics – use of technology to study and store biological data
C) Biophysics – study of biological processes through physics
D) Biology – study of life
2) Based on hierarchical levels of biological organization, which of these choices represents the
broadest level?
A) Endocrine system
B) 3 toed sloths
C) School of piranhas
D) Amazon Basin
E) Jaguars, giant anteaters, macaws, capybaras
3) Experiments are carried out to test a hypothesis by changing one variable at a time and
including an unchanged variable termed a(n) ________.
A) experimental variable
B) altered variable
C) control
D) stable variable
4) The method of reasoning that uses construction of general principles by careful examination
of many specific cases is called:
A) deductive reasoning.
B) theoretical reasoning.
C) hypothetical reasoning.
D) inductive reasoning.
E) experimental reasoning.
5) Dr. Ratard was trying to determine the cause of a mysterious epidemic affecting fish in the
gulf of New Mexico. His proposal that the deaths were caused by an organism called a protist is
considered a(n) ________
A) experiment.
B) hypothesis.
C) conclusion.
D) theory.
E) data set.

6) After Darwin concluded his voyage on the Beagle, he proposed that the process of natural
selection was a mechanism for:
A) artificial selection.
B) evolution.
C) sexual selection.
D) speciation.
E) overpopulation of finches on the Galapagos Islands.
7) A scientific theory is:
A) a suggested explanation that accounts for observations.
B) a way to organize how we think about a problem.
C) a concept that is supported by experimental evidence that explains the facts in an area of
study.
D) a way to understand a complex system by reducing it to its working parts.
8) What common life characteristic would cells from a daisy, bacteria, and a dog all have?
A) DNA
B) cell walls
C) organs
D) ability to conduct photosynthesis
9) A yellow jacket, an insect in the order Hymenoptera, stung me. A wasp, an insect in
Hymenoptera, stung me. A hornet, an insect in Hymenoptera, stung me. I see a pattern. All

insects in this order must have stingers. What type of reasoning does this represent?
A) inductive reasoning
B) deductive reasoning
C) reductionism
D) comparative reasoning
10) You explain to your study group that a hypothesis is:
A) an explanation that accounts for careful observations.
B) a proposition that will be true and fits the known facts.
C) a theory.
D) constant over time.
11) A suggested explanation that might be true and is subject to testing by further observations is
a(n):
A) experiment.
B) generality.
C) hypothesis.
D) scientific principle.
E) theory.

12) Based on the literature, you hypothesize that students in traditional biology lectures will have
the same grades as students in online biology lectures. You decide to test your hypothesis by
comparing grades of students in traditional and online biology lectures over a semester. As a
result of the experiment, you observe that the grades in the traditional lectures and the grades in
the online lectures are not significantly different. What do these observations allow you to do?
A) reject the hypothesis
B) accept the hypothesis without further question
C) develop a scientific theory
D) reject the null hypotheses
13) Your microwave will not turn on, and you speculate that a circuit breaker in the house has
been tripped. In scientific terminology, the steps would be described as:
A) forming conclusions from the results of experiments.
B) developing an observation based on a hypothesis.
C) developing a hypothesis based on an observation.
D) testing a prediction generated from a hypothesis.
14) A student poses the question: How does the presence of dissolved salt affect the freezing
point of water? To answer this question, the student set up two conditions. In the first condition,
the student added salt to water in a container and referred to this condition as the variable. In the
second condition, the student did not add any salt to water in a second container and referred to
this condition as the control. The student took both containers and attempted to freeze the water
at various temperatures to assess the freezing point. Would this be a valid experiment?
NURSIN
A) Yes, because there is more than one variable.
B) Yes, because there is one variable and a control
C) No, because there is not more than one variable
D) No because there is only one variable and a control
15) Karl Popper suggested that scientists use "imaginative preconception," which means that
successful scientists:
A) often predict the outcome of experiments.
B) cannot predict the outcome of experiments.
C) do not need to do experiments to test their ideas.
D) do not keep records of experiments that fail.
E) only perform applied research.
16) The proposal that one type of organism can change gradually into another type over a long
period of time is known as:
A) evolution.
B) natural history.
C) preconception.
D) preservation.
